"Explore more" section may be more appropriate for the educator than the student.

About the Science

Four slides that introduce the greenhouse effect and some greenhouse gases. Simple visual and text explanation of the natural greenhouse effect and how human activities are intensifying this effect.

Comment from expert scientist: It is well built and very clear. It is clear and simple in the way it explains what greenhouse effect is, what the main greenhouse gases are, and what effect they exert.

About the Pedagogy

The "Explore More" button contains links to a video about the causes of global warming, a map of global warming effects, and a quiz about climate change.

The extra material is good. But it is not clear how one could answer all the questions correctly in the quiz. There are some problems with the wording of the quiz, which may be misleading.
